Following statements are regarding to the fluidity of a bilayer.
A. A lipid bilayer cools below a characteristic transition temperature, it undergoes a sort of phase change in which it becomes a liquid; that is, it loses its fluidity.
B. Above the transition temperature, the highly mobile lipids are in a state known as a liquid crystal.
C. The bilayer is thicker in the gel state than in the liquid crystal state due to the stiffening of the hydrocarbon tails at lower temperatures.
D. The transition temperature of a bilayer decreases with the chain length and the degree of saturation of its component fatty acid residues for the same reasons that the melting points of fatty acids increase with these quantities.
